TAG-ENVELOP.

present invention has in view are: to enable an envelop of the charactermentioned to be openedin transit for examination and reclosed to preventthe loss of the contents; to strengthen the structure of the envelop toprevent the destruction of the same; and to reduce the cost ofmanufacture of envelops of the. character mentioned.

I Description. I i As seen in the drawings, a reinforcing patch 15 isadhered to the envelop closure flap 16 and envelop body portion 17, saidbody extending across the bending line 18 of the said flap.

cut edge 21 thereof. Attention is drawn to the fact that the cut' edges21 and 22 of the flap 20 and flap 16, respectively, are comple mentaryin shape,thatis, the edge of each flap of each envelop is complementaryto the edge of the back of they envelop next successively separated fromthe Iweb from which envelop blanks are formed. Therefore it is obviousthat the patches 15 and 19 have complementary relation each to theother.

uring the course of manufacture of the envelop and after the patches 1-5and 19 have been adhered to the blank, the perforations 23, 24: and 25are punched, said perforations extending through said patches and thesuperposed envelop material. tions are so arranged that when the flap 16three perforations aline as shown best in Fig. 4 of the drawings. henenvelope constructed as above described are closed, a tie string of any.suitable form may be'ex'tended through the alined perforations 23, 24and 25 and in this position the envelop may be temporarily locked.

In the modified formshown in Fig. 2 of the drawings, ing the envelop toa package. These envelops are mostly intended for bills of lading orinstructions or directions, to gain access to which it is foundconvenient to loosen the flap after the same has been closed and startedfrom its To this end, a provided, said tag incorporating the perforation23 by being partially separated from the flap 16 by 'a number of closelyassociated perforations 27.

In service, a tack 28 or other suitable fastening device is driventhrough the perforations23, 24.- and and into the article to Theseperforaprovision is made for attachoriginal point of departure.partially separated tag 26 is which the envelop is attached, the head ofI the tack extending over the side edges of the tag 26. p p

When, now, an envelop so constructed reaches the'station where it is tobe'inspectof'perforations 27 to free the said flap.- A perforation 30,as shown best in Fig. 6 of the drawings, is formed in the flap where thetag 26 previously existed. It will be noted, however, that the tag 28,tack 26, and body portion 17 of the envelop are held beneath the head ofthe tack 28. After withdrawing the contents of the enthe tag 26 on a.Sal

volop when thus attached to a parcel, the same are returned to theenvelop and the flap 29 is tucked under the free edge of the back of theenvelop.

The modified form of the invention shown in Fig. 3 provides an extrareinforcing patch 31 which adhered to the back and body of the envelopadjacent the folded edge there-. of. After the envelop back portion 20has been folded over on the bodyportion 17, the patch 31 is punched toform alined perforations When, now, the envelop is closed, the retainingcord is threaded through the perforations 32, :23, 2e and 25, then tied,and, if necessary, the ends thereof are sealed.

Ulaz'ma' 1. An envelop comprising a body, flap and back of equal Widthand integrally connected, the raw edge of said flap being complementaryto the raw edge of said back for facilitating the severing ofsaidenvelop from a continuous web; a reinforcing patch permanently attachedto said flap and adjacent portion of said body for extending acre-s theline of fold of said flap on said body, said patch and the flap and bodysuperposed thereon having perforations formed therethrough, saidperforations being disposed for alining when said flap is folded oversaid body; and a patch permanently attached to said back adjacent theraw edge thereof, said patches having raw edges corresponding with'theraw edges of said flap and said back.

2. An envelop comprising a body, fiap and back of equal Width andintegrally con nected, the raw edge of said flap being complementary tothe raw edge of said back for facilitating the severing of said envelopfrom a continuous Web; a reinforcing patch ermanently attached to saidflap and adjacent portion of said body for extending across the line offold of said flap on said body, said patch and the flap and bodysuperposed thereon having perforations formed therethrough, saidperforations being disposed for alining when said flap is folded oversaid body; and a patch permanently attached to said back adjacent theraw edges thereof, said. patches having raw edges oorrespondinv with theraw edges of :aid flap and said back, said raw edges being coincidentlyformed by the single operation of a device employed for separating innersurface thereof, said patch extending across the line of fold formingthe bottom of said envelop and extending from the said line of fold; andmeans for closing said en-.
